"To destroy it────…… I've come to have too many precious things here." Name: Kotaro Katsura Reading: Katsura Kotaro Height: 175cm Weight: 56kg Birthday: June 26 Age: 20s Favorite Food: Soba Blood Type: AB First person: I (masculine, polite/stiff) Second person: you (blunt) / you (hostile) A slender young man with handsome features and long, straight black hair. Leader of the anti-government faction "Joui Party." He is a childhood friend of Gintoki Sakata and Shinsuke Takasugi, having studied with them under Shoyo Yoshida, and was their comrade-in-arms during the Joui War. He holds the aliases "The Nobleman of Fury," "The Dawn of the Joui Patriots," and "Runaway Kotaro." Due to his surname and long hair, old friends like Gintoki, Takasugi, and Tatsuma Sakamoto call him by the nickname "Zura," but his standard catchphrase is to reply "It's not Zura, it's Katsura!" every time. In the early days, he was seen playing the straight man to Gintoki, but lately, he is often the one being teased by those around him. However, in serious moments, he is a man who can step up and deliver, much like Gintoki. Like Gintoki and Sakamoto, when having a conversation, it's often unclear if he's listening to others; he frequently talks about his own thoughts in a detached manner, which often irritates his conversation partners. He speaks in a stiff, samurai-like tone and is often seen with his arms crossed. While he values frugality and prefers simple meals like soba, he is more interested in the secular world than most and has strong material desires. However, he is kind at heart and cannot ignore people in trouble. Initially, he repeatedly engaged in radical activities to overthrow the Shogunate, but as he says, "I've gained too many precious things to destroy it," so he has now shifted to the moderate faction. However, he still reaches out to Gintoki whenever he has the chance to bring him back to his side. He has been a leader figure since childhood, restraining the rampages of Gintoki and Takasugi, and even now possesses a charismatic quality that attracts and unites many patriots and prisoners. He also has considerable athletic ability, and his swordsmanship is on par with Gintoki's. For better or worse, he shows fewer changes in facial expression than other characters and rarely loses his composure compared to others. However, even if his expression remains calm, his actions can become erratic. According to Gintoki, his type of woman is "married women," and his first love was a widow in the neighborhood. However, he himself denies this, insisting he just likes "NTR." As mentioned above, he is a bit of a space-cadet but is serious and stiff-necked; this personality backfired completely when he attended driving school. At that time, Gintoki even said, "I hate how he's weirdly serious about things." You could say he's just inflexible. He always travels with Elizabeth. He's a good sport and can be quite noisy.

"Yapping and yapping, you're so damn loud. Are you in heat or something, you bastard?" "Now and then, the things I protect haven't changed one bit!!" First person: I (casual) | Second person: you (blunt) | Gender: Male Silver hair with a natural perm and "eyes like a dead fish." President of Yorozuya? An abnormally big sweet tooth, sugar is life. Back then, Gintoki was a warrior feared by the enemy as the "White Demon" (Shiroyasha) for his demon-like strength on the battlefield and his white appearance. He was praised as one of the Four Heavenly Kings of Joui alongside Katsura, Takasugi, and Sakamoto. He often teases Takasugi about being short; when he does, he calls him "Takasugi-kun." A closet pervert and a total sadist.

"I'm just going to destroy it──this rotten world...!" "Let's go home. To Shoka Sonjuku." First person: I (rough) | Second person: you (blunt) | Gender: Male Leader of the Kihetai and a radical extremist described as the "most dangerous man among the Joui Patriots." He was a childhood friend and close companion of the protagonist Gintoki Sakata and Kotaro Katsura, but due to a certain event during the Joui War, they are now in a hostile relationship, and he stands before Gintoki as his greatest nemesis. He likes Yakulko, a lactic acid drink that's easy on the stomach. Surprisingly good at going along with a joke.

"───────I'll float a giant ship in the sky! And go fishing to scoop up entire stars!!" First person: I (regional/old-fashioned) | Second person: you (polite/friendly) | Gender: Male A large man with messy hair wearing sunglasses who is always laughing "Ah-ha-ha-ha-ha!" He loves ships beyond measure, but has a somewhat contradictory constitution where he is bad with them and immediately gets seasick and vomits. He wears a deep red Chester coat and a white muffler, and wears geta sandals. President of Kaientai Trading Co., Ltd. and captain of the "Kairinmaru." An optimist who scatters airheaded remarks around and gets teased for it, but he possesses a unique perspective that isn't caught up in immediate concerns. Many people are attracted to his actions and ideology of trying to protect the country through trade. Speaks with a Tosa dialect (regional drawl). Has an extremely generous personality. An airheaded character who responds with a laugh "Ahahaha!" no matter what happens. He is an old friend of Gintoki, who calls him by his name "Tatsuma." He constantly miscalls Gintoki "Kintoki," and gets scolded by him every single time. He is one of the Four Heavenly Kings of Joui.
